I don't have experience with this product but I would be concerned with using it due to the weight a passenger would add. My ebike has a max weight capacity of 300lbs. Other models and brands have lower ratings but even at a 300lb rating a passenger and rider could easily overload the bike and brakes. Ignoring possible injuries, the lifetime frame warranty on my ebike would be voided.
Handling is another concern. The passenger center of gravity is fairly high. I can see where this would make turns much more difficult.
YRMV, but I'd be very cautious about this add on.
Cargo ebikes may be OK with the added load, but even then I'd verify the bike's ratings first.
Thanks, before buying the Flash, I was looking at a number of bikes built to have an extra rider, such as those from RadPower, Juiced, and Super73, which is what directed me towards the idea or 2-riders, but ultimately I did want a more standard bike frame, pedal-assist concept bike, rather than a cargo- or moped-style frame. I'll definitely be very cautious with any add-on.
I've been trying to determine whether a
banana seat (example: 26" lowrider seat) with sissy bars would distribute the weight differently than the companion bike seat (not sure whether that is compatible with this bike), just as an idea. I'd be interested in what people thing.
Imagining that the banana seat would allow for more weight to distribute onto the seat post while still having the sissy bar, I'm wondering whether that would make for a seat that relies more directly on the structure of the bike (the seatpost and the center of the frame) as opposed to the Companion style where appears distributed on a rack and the back tire.
Companion bike seat makes
ebike pegs to use with their seat, but you could also use them on their own.
That would allow weight to be distributed to four points (seatpost, sissy bars, left axle peg, right axle peg). It is true that the last three points of weight distribution are all on the back axle/back wheel, which means the earlier concern is still an issue / danger.
The weight limit of the Flash ebike is 300lbs. I weight around 170lbs on average, and my gf is about 130, meaning that we would be within the weight limit of the bike as a whole, but just making the center of gravity further back than normal. So, it stands to reason that this could be a find setup.
I'm hesitant to try anything because my bike is new, and I need it for much more intensive 1-rider riding, but maybe a year down the line, I'll settle on an idea to try out.
